Abstract

The utility model discloses a bending and flattening mould for a bender, which belongs to the field of machining moulds. The bending and flattening mould for the bender comprises an upper mould and a lower mould, a V-shaped mould tip is arranged at the lower end of the upper mould, a plane provided with a right side of the V-shaped mould tip is a second inclined surface, the right side of the upper mould includes a first vertical surface, a first inclined surface, a second vertical surface and a second inclined surface from top to bottom, a 90-degree step is arranged on a transition portion between the first inclined surface and the second inclined surface, a rectangular groove is arranged on the lower mould, and the V-shaped mould tip can be fittingly inserted into the rectangular groove. The bending and flattening mould can be used for bending and flattening workpieces which can be originally bent and flattened by two moulds, mould replacement time is saved, cost is saved for enterprises, and the labor intensity is relieved for workers.

Description

The bending machine die that a kind of bending band flattens

Technical field

The utility model belongs to the machine dies field, more particularly, relates to a kind of bending machine die that can realize that bending flattens again.

Background technology

People are various to the bender requirement of products now, the increase of demand, and under the situation that technology is constantly brought forth new ideas, the update of product is rapider, and rich choice of products is colorful.The development of bender is also developing to simple and easy, cheap numerical control bender, thereby can satisfy demand at all levels not only towards development high-end, H.D numerical control.

Bender is divided into manual bending machine, hydraulic bending press and numerical control bender.Manual bending machine is divided into mechanical manual bending machine and electric and hand bender again.Hydraulic bending press can be divided into again by the method for synchronization: turn round axle synchronously, the synchronous and electric liquid of machine liquid is synchronous; Hydraulic bending press can be divided into again by motion mode: upper dynamic, lower-moving type.Hydraulic bending press can be used for can also metallic plate being pressed, be converted into various difform workpiece as long as the operator mixes the mould of various different structures, shape outside the various sheet metals of bending, when being equipped with corresponding equipment, also can supply the usefulness of punching.Multi-form according to bending, section configuration can provide a variety of purposes; Hydraulic bending press can also utilize particular manufacturing craft to carry out bending, reaches the bending requirement of special shape.

Bending pressing die again is a kind of mould very commonly used of electrical apparatus industry; Bending of processing in the past flattens workpiece again and need change two and put bed die and could accomplish; First mold is used for being bent into an acute angle to workpiece, uses the second cover flattening die tool that workpiece is flattened then, is processed into the workpiece of shape as shown in Figure 1; But this way needs two molds to accomplish, and cost is higher.

Summary of the invention

The problem that solves

To the deficiency of prior art, provide a kind of not only can bending but also can flatten the mould of workpiece.

Technical scheme

The bending machine die that a kind of bending band flattens; Comprise mold and bed die; The lower end of described mold is a V-type mould point; The plane, right flank place of said V-type mould point is second inclined plane, and the right flank of said mold is followed successively by first vertical plane, first inclined plane, second vertical plane and second inclined plane from the top down, and described first inclined plane and second inclined plane are in one plane; Such structural design can make workpiece when the bending perk, touch mutually with second inclined plane, avoids the workpiece out-of-flatness.Transition portion between described first inclined plane and second inclined plane is 90 ° a step; Said bed die is provided with rectangular recess, V-type mould point can adaptive insertion rectangular recess in.

The degree of depth of rectangular recess is greater than the lower extreme point of the V-type mould of the cope match-plate pattern point vertical range to the step horizontal plane.The horizontal plane of step and the upper surface of bed die can closely contact when flattening workpiece like this.During use, at first plate workpiece is put between mold and the bed die, the V-type mould point of mold moves down under the drive of motor in the groove that inserts bed die, has at this moment accomplished the bending of workpiece; Remove mold; The workpiece of bending is taken out; And be placed on the horizontal end face on bed die upper surface groove right side, starting bender and make the V-type mould point of mold under the drive of motor, move down the rectangular recess of inserting bed die again, mold is in the decline process; The horizontal plane of mold step press down with the horizontal end face of the upper surface rectangular recess both sides of bed die constantly near, accomplish the applanation process of plate workpiece.

Beneficial effect

The utility model is than the advantage of prior art:

(1) mould that uses the utility model bending to flatten again, a mold not only can bendings but also can have been accomplished pressing work, had accomplished the work that former needs two molds could be accomplished, and had practiced thrift machine cost;

(2) use the mould of the utility model to save the lead-time, for the workman has alleviated labour intensity;

(3) the utility model is simple in structure, is easy to make.

The specific embodiment

Embodiment 1

The structure of the utility model is as shown in Figure 2; The bending machine die that a kind of bending band flattens comprises mold 1 and bed die 4, and the lower end of described mold 1 is a V-type mould point 7; The angle of V-type mould point 7 is 27 °; The plane, right flank place of said V-type mould point 7 is second inclined plane 3, and the right flank of said mold is followed successively by first vertical plane 8, first inclined plane 2, second vertical plane 9 and second inclined plane 3 from the top down, and described first inclined plane 2 and second inclined plane 3 are in one plane.Transition portion between described first inclined plane 2 and second inclined plane 3 is 90 ° a step 6; Said bed die 1 is provided with rectangular recess 5, V-type mould point 7 can adaptive insertion rectangular recess 5 in.

The degree of depth of groove 5 is greater than the distance of V-type mould point 7 to the turning of step 6.The horizontal plane of step and the upper surface of bed die can closely contact when flattening workpiece like this.During use; As shown in Figure 3, at first plate workpiece to be put between mold 1 and the bed die 4, the V-type mould of mold 1 point 7 moves down under the drive of motor in the groove 5 that inserts bed die 4; When workpiece bends to 30 ° of angles, stop to insert, at this moment accomplished the bending of workpiece; Remove mold 1, as shown in Figure 4, with the workpiece taking-up of bending; And be placed on the horizontal end face on bed die 4 upper surface grooves 5 right sides; Start bender and make the V-type mould point 7 of mold 1 under the drive of motor, move down the rectangular recess 5 of inserting bed die 4 again, mold 1 is in the decline process, and the horizontal plane of the step 6 of mold 1 presses down; With the horizontal end face of the upper surface of bed die 4 constantly near; Accomplish the applanation process of workpiece, state is as shown in Figure 5, obtains workpiece as shown in Figure 1 at last.
